"Dwarf American Toad" is a separate species than "American Toad" although they look very similar. The American Toad is much bigger as an adult. When our toad was just out of the water (a "toadlet"
it was REALLY small. Smaller than your little fingernail....so small, a mosquito was too large for it to eat. We fed the toad things like tiny insects swept off wood surfaces and aphids. Full grown, it can easily sit on a half dollar with no overhang. I'm not sure what the range of the Dwarf American Toad is...you might want to check that out to see if it is something you would find in your region just to be sure. I'm no expert on 'fibs...it might be the case that you found a juvenile American Toad, but don't know for sure how the size of a juvenile American Toad compares to a full-grown Dwarf American Toad. Maybe someone with more familiarity of these two toads will comment on this question.
